The science tutor later told an officer: “I thought I was being smart.”

Bonkoski is out on bail accused of eight charges – three of institutional sexual assault, three of unlawful contact with a minor and one each of corrupting minors and criminal use of a communication facility.

She has resigned from Owen J. Roberts High School, Pottstown, Pennsylvania, after education bosses demanded she quit following her arrest.

She became ‘obsessed’ with one of her students at Owen J. Roberts High School, in Pennsylvania

Acting school district superintendent Anthony Costello said: “Upon learning of the filing of these charges, the school district asked for, and received, Bonkoski’s immediate resignation from her employment as a teacher.”

He added: “The school district has fully co-operated with the investigations conducted by those agencies regarding the allegations, and will continue to do so throughout the criminal prosecution of this matter.”

Bonkoski’s alleged involvement with the pupil started in December, 2015.

Police received a complain last March that he was getting harassing texts from Bonkoski, according to police files.

He told the detective Christine Beiler that Bonkoski had been his teacher in his freshman year and, although she initially sent him messages about schoolwork. they became more frequent and personal in nature.

In a follow-up interview on July 21, Beiler said the teen told her he was upset with himself because he had “cheated” on his girlfriend with Bonkoski.

Their initial contact became “extreme” when she began giving him rides home from school in 2016, he said.

They snogged more than once, leaving him “in shock” because he “never thought he would kiss a teacher.”

Detective Beiler’s documents say: “He was worried that he wouldn’t get rides home anymore if he stopped kissing (Bonkoski,)

He said he slept at her house sometime in 2015 and discussed oral sex.

He tried to stop the contact at some point but said Bonkoski would continue to call and send texts.

Another detective, Joseph Walton, met the boy’s girlfriend and her mother, reports the Daily Times.

And the girl showed him texts she had captured from Bonkoski to the teenager in March.

One read that she “was kinda hoping you would’ve called me back last night. I really need to talk.”

Another referred to a fundraiser at the school which she had wanted to attend with him.

Checks with the phone provider apparently showed it was used only to communicate with the teenager, mainly from the school or near her home in Stowe.

Bonkoski confessed about her conduct with the boy when confronted by a state police trooper, according to the files.

“When the victim stopped talking to her, she started to ‘bombard’ him with memories of him visiting her classroom,” they say.

Bonkoski was in her second year teaching at the high school. She previously “spent several years teaching science in Miami, Florida, and before that in West Philadelphia,” said her online profile before it was deleted.
